Record coral cover doesn’t necessarily mean the Great Barrier Reef is in good health (despite what you may have heard)

<p>In what seems like excellent news, coral cover in parts of the Great Barrier Reef is at a record high, according to <a href="https://www.aims.gov.au/information-centre/news-and-stories/highest-coral-cover-central-northern-reef-36-years" target="_blank" rel="noopener">new data</a> from the Australian Institute of Marine Science. But this doesn’t necessarily mean our beloved reef is in good health.</p> <p>In the north of the reef, coral cover usually fluctuates between 20% and 30%. Currently, it’s at 36%, the highest level recorded since monitoring began more than three decades ago.</p> <p>This level of coral cover comes hot off the back of a <a href="https://theconversation.com/another-mass-bleaching-event-is-devastating-the-great-barrier-reef-what-will-it-take-for-coral-to-survive-180180" target="_blank" rel="noopener">disturbing decade</a> that saw the reef endure six mass coral bleaching events, four severe tropical cyclones, active outbreaks of crown-of-thorns starfish, and water quality impacts following floods. So what’s going on?</p> <p>High coral cover findings <a href="https://theconversation.com/a-lot-of-coral-doesnt-always-mean-high-biodiversity-10548" target="_blank" rel="noopener">can be deceptive</a> because they can result from only a few dominant species that grow rapidly after disturbance (such as mass bleaching). These same corals, however, are extremely susceptible to disturbance and are likely to die out within a few years.</p> <h2>The data are robust</h2> <p>The <a href="https://peerj.com/articles/4747/" target="_blank" rel="noopener">Great Barrier Reef spans</a> 2,300 kilometres, comprising more than 3,000 individual reefs. It is an exceptionally diverse ecosystem that features more than 12,000 animal species, plus many thousand more species of plankton and marine flora.</p> <p>The reef has been teetering on the edge of receiving an “in-danger” <a href="https://theconversation.com/not-declaring-the-great-barrier-reef-as-in-danger-only-postpones-the-inevitable-164867" target="_blank" rel="noopener">listing</a> from the World Heritage Committee. And it was <a href="https://theconversation.com/this-is-australias-most-important-report-on-the-environments-deteriorating-health-we-present-its-grim-findings-186131" target="_blank" rel="noopener">recently described</a> in the State of the Environment Report as being in a poor and deteriorating state.</p> <p>To protect the Great Barrier Reef, we need to routinely monitor and report on its condition. The Australian Institute of Marine Science’s long-term monitoring program has been collating and delivering this information since 1985.</p> <p>Its approach involves surveying a selection of reefs that represent different habitat types (inshore, midshelf, offshore) and management zones. The <a href="https://www.aims.gov.au/monitoring-great-barrier-reef/gbr-condition-summary-2021-22" target="_blank" rel="noopener">latest report</a> provides a robust and valuable synopsis of how coral cover has changed at 87 reefs across three sectors (north, central and south) over the past 36 years.</p> <h2>The results</h2> <p>Overall, the long-term monitoring team found coral cover has increased on most reefs. The level of coral cover on reefs near Cape Grenville and Princess Charlotte Bay in the northern sector has bounced back from bleaching, with two reefs having <a href="https://www.aims.gov.au/sites/default/files/2022-08/AIMS_LTMP_Report_on%20GBR_coral_status_2021_2022_040822F3.pdf" target="_blank" rel="noopener">more than 75% cover</a>.</p> <p>In the central sector, where coral cover has historically been lower than in the north and south, coral cover is now at a region-wide high, at 33%.</p> <p>The southern sector has a dynamic coral cover record. In the late 1980s coral cover surpassed 40%, before dropping to a region-wide low of 12% in 2011 after Cyclone Hamish.</p> <p>The region is currently experiencing outbreaks of crown-of-thorns starfish. And yet, coral cover in this area is still relatively high at 34%.</p> <p>Based on this robust data set, which shows increases in coral cover indicative of region-wide recovery, things must be looking up for the Great Barrier Reef – right?</p> <h2>Are we being catfished by coral cover?</h2> <p>In the Australian Institute of Marine Science’s report, reef recovery relates solely to an increase in coral cover, so let’s unpack this term.</p> <p>Coral cover is a broad proxy metric that indicates habitat condition. It’s relatively easy data to collect and report on, and is the most widely used monitoring metric on coral reefs.</p> <p>The finding of high coral cover may signify a reef in good condition, and an increase in coral cover after disturbance may signify a recovering reef.</p> <p>But in this instance, it’s more likely the reef is being dominated by only few species, as the report states that branching and plating Acropora species have driven the recovery of coral cover.</p> <p>Acropora coral are renowned for a “boom and bust” life cycle. After disturbances such as a cyclone, Acropora species function as pioneers. They quickly recruit and colonise bare space, and the laterally growing plate-like species can rapidly cover large areas.</p> <p>Fast-growing Acropora corals tend to dominate during the early phase of recovery after disturbances such as the recent series of mass bleaching events. However, these same corals are often susceptible to wave damage, disease or coral bleaching and tend to go bust within a few years.</p> <p>Inferring that a reef has recovered by a person being towed behind a boat to obtain a rapid visual estimate of coral cover is like flying in a helicopter and saying a bushfire-hit forest has recovered because the canopy has grown back.</p> <p>It provides no information about diversity, or the abundance and health of other animals and plants that live in and among the trees, or coral.</p> <h2>Cautious optimism</h2> <p>My <a href="https://theconversation.com/almost-60-coral-species-around-lizard-island-are-missing-and-a-great-barrier-reef-extinction-crisis-could-be-next-163714" target="_blank" rel="noopener">study</a>, published last year, examined 44 years of coral distribution records around Jiigurru, Lizard Island, at the northern end of the Great Barrier Reef.</p> <p>It suggested that 28 of 368 species of hard coral recorded at that location haven’t been seen for at least a decade, and are at risk of local extinction.</p> <p>Lizard Island is one location where coral cover has rapidly increased since the devastating 2016-17 bleaching event. Yet, there is still a real risk local extinctions of coral species have occurred.</p> <p>While there’s no data to prove or disprove it, it’s also probable that extinctions or local declines of coral-affiliated marine life, such as coral-eating fishes, crustaceans and molluscs have also occurred.</p> <p>Without more information at the level of individual species, it is impossible to understand how much of the Great Barrier Reef has been lost, or recovered, since the last mass bleaching event.</p> <p>Based on the coral cover data, it’s tempting to be optimistic. But given more frequent and severe heatwaves and cyclones are predicted in the future, it’s wise to be cautious about the reef’s perceived recovery or resilience.</p> <p><strong>This article originally appeared on The Conversation.</strong></p> <p><em>Image: Shutterstock</em></p>

Past policies have created barriers to voting in remote First Nations communities

No, sunscreen chemicals are not bleaching the Great Barrier Reef

<p>For the sixth time in the last 25 years, the Great Barrier Reef <a href="https://www.gbrmpa.gov.au/the-reef/reef-health" target="_blank" rel="noopener">is bleaching</a>. During bleaching events, people are quick to point the finger at different causes, including <a href="https://owlcation.com/stem/Coral-Bleaching-and-Oxybenzone-Choose-Your-Sunscreen-Carefully" target="_blank" rel="noopener">sunscreen</a>.</p> <p>Why sunscreen? Some active ingredients can wash off snorkelers and into the reef, contaminating the area. So could this be the cause of the Barrier Reef’s bleaching?</p> <p>In a word, no. I reviewed the evidence for sunscreen as a risk to coral in my <a href="https://www.publish.csiro.au/CH/CH21236" target="_blank" rel="noopener">new research</a>, and found that while chemicals in sunscreen pose a risk to corals under laboratory conditions, they are only found at very low levels in real world environments.</p> <p>That means when coral bleaching does occur, it is more likely to be due to the marine heatwaves and increased water temperatures that have come with climate change, as well as land-based run-off.</p> <p><strong>Why have we been concerned over the environmental impact of sunscreens?</strong></p> <p>After we apply sunscreen, the active ingredients can leach from our skin into the water. When we shower after swimming, soaps and detergents can further strip the these sunscreen chemicals off and send them into our waste water systems. They pass through treatment facilities, which cannot effectively remove them, and end up in rivers and oceans.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/454296/original/file-20220325-21-1agae0v.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/454296/original/file-20220325-21-1agae0v.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/454296/original/file-20220325-21-1agae0v.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/454296/original/file-20220325-21-1agae0v.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/454296/original/file-20220325-21-1agae0v.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/454296/original/file-20220325-21-1agae0v.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/454296/original/file-20220325-21-1agae0v.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/454296/original/file-20220325-21-1agae0v.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=3 2262w" alt="hands putting on sunscreen" /></a><figcaption><span class="caption">Sunscreen isn’t the cause of the coral bleaching.</span> <span class="attribution">Shutterstock</span></figcaption></figure> <p>It’s no surprise, then, that sunscreen contamination has been detected in freshwater and seas across the globe, from <a href="https://pubmed.ncbi.nlm.nih.gov/15996716/" target="_blank" rel="noopener">Switzerland</a> to <a href="https://link.springer.com/article/10.1007/s11356-015-5174-3" target="_blank" rel="noopener">Brazil</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/27235899/" target="_blank" rel="noopener">Hong Kong</a>. Contamination is highest in the summer months, consistent with when people are more likely to go swimming, and peaks in the hours after people have finished swimming.</p> <p>Four years ago, the Pacific island nation of Palau made world headlines by announcing plans to <a href="https://www.theguardian.com/world/2018/nov/02/pacific-island-to-introduce-world-first-reef-toxic-sunscreen-ban" target="_blank" rel="noopener">ban all sunscreens</a> that contain specific synthetic active ingredients due to concern over the risk they posed to corals. <a href="https://www.cntraveler.com/story/these-destinations-are-banning-certain-sunscreens" target="_blank" rel="noopener">Similar bans</a> have been announced by Hawaii, as well a number of other popular tourist areas in the Americas and Caribbean.</p> <p>These bans are based on independent scientific studies and <a href="https://coralreefpalau.org/wp-content/uploads/2017/10/CRRF-UNESCO-Sunscreen-in-Jellyfish-Lake-no.2732.pdf" target="_blank" rel="noopener">commissioned reports</a> which have found contamination from specific active ingredients in sunscreen in the water at beaches, rivers and lakes.</p> <p>Notably, the nations and regions which have banned these active ingredients, like Bonaire and Mexico, have local economies heavily reliant on summer tourism. For these areas, coral bleaching is not only an environmental catastrophe but an economic loss as well, if tourists choose to go elsewhere.</p> <p><strong>How do we know sunscreen isn’t the issue?</strong></p> <p>So if contamination concerns over these active ingredients are warranted, how can we be sure they’re not the cause of the bleaching in the Great Barrier Reef?</p> <p>Put simply, the concentrations of the chemicals are too low to cause the bleaching.</p> <p>The synthetic ingredients used in most products are highly <a href="https://www.corrosionpedia.com/definition/653/hydrophobic#:%7E:text=Hydrophobic%20is%20a%20property%20of,Oils%20and%20fats%20are%20hydrophobic." target="_blank" rel="noopener">hydrophobic</a> and <a href="https://www.greenfacts.org/glossary/jkl/lipophilic.htm" target="_blank" rel="noopener">lipophilic</a>. That means they shun water and love fats, making them hard to dissolve in water. They’d much prefer to stay in the skin until they break down.</p> <p>Because of this, the levels found in the environment are very low. How low? Think nanograms per litre (a nanogram is 0.000000001 grams) or micrograms per litre (a microgram is 0.00001 grams). Significantly higher levels are found only in waste water treatment sludge and some sediments, not in the water itself.</p> <p>So how do we reconcile this with studies showing sunscreen can damage corals? Under laboratory conditions, many active ingredients in sunscreen have been found to damage corals as well as <a href="https://pubmed.ncbi.nlm.nih.gov/22828885/" target="_blank" rel="noopener">mussels</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/17889917/#:%7E:text=BP%2D2%20was%20accumulated%20in,and%20female%20fish%20were%20observed." target="_blank" rel="noopener">fish</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/24359924/" target="_blank" rel="noopener">small crustaceans</a>, and plant-like organisms such as <a href="https://www.sciencedirect.com/science/article/abs/pii/S0269749111006713" target="_blank" rel="noopener">algae and phytoplankton</a>.</p> <p>The key phrase above is “under laboratory conditions”.

5 major heatwaves in 30 years have turned the Great Barrier Reef into a bleached checkerboard

<p>Just 2% of the Great Barrier Reef remains untouched by bleaching since 1998 and 80% of individual reefs have bleached severely once, twice or three times since 2016, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0960982221014901">our new study</a> reveals today.</p> <p>We measured the impacts of five marine heatwaves on the Great Barrier Reef over the past three decades: in 1998, 2002, 2016, 2017 and 2020. We found these bouts of extreme temperatures have transformed it into a checkerboard of bleached reefs with very different recent histories.</p> <p>Whether we still have a functioning Great Barrier Reef in the decades to come depends on how much higher we allow global temperatures to rise. The bleaching events we’ve already seen in recent years are a result of the world warming by 1.2℃ since pre-industrial times.</p> <p>World leaders meeting at the climate summit in Glasgow must commit to more ambitious promises to drastically cut greenhouse gas emissions. It’s vital for the future of corals reefs, and for the hundreds of millions of people who depend on them for their livelihoods and food security.</p> <h2>Coral in a hotter climate</h2> <p>The Great Barrier Reef is comprised of more than 3,000 individual reefs stretching for <a href="https://www.gbrmpa.gov.au/the-reef/reef-facts">2,300 kilometres</a>, and supports more than 60,000 jobs in reef <a href="https://www.gbrmpa.gov.au/our-work/Managing-multiple-uses/tourism-on-the-great-barrier-reef">tourism</a>.</p> <p>Under climate change, the frequency, intensity and scale of climate extremes is changing rapidly, including the record-breaking marine heatwaves that cause corals to bleach. Bleaching is a stress response by overheated corals, where they lose their colour and many struggle to survive.</p> <p>If all new COP26 pledges by individual countries are actually met, then the projected increase in average global warming could be brought down <a href="https://www.climate-resource.com/tools/ndcs">to 1.9℃</a>. In theory, this would put us in line with the goal of the Paris Agreement, which is to keep global warming below 2℃, but preferably 1.5℃, this century.</p> <p>However, it is still not enough to prevent the <a href="https://www.ipcc.ch/sr15/chapter/spm/">ongoing degradation</a> of the world’s coral reefs. The damage to coral reefs from anthropogenic heating so far is very clear, and further warming will continue to <a href="https://www.science.org/doi/10.1126/science.aan8048">ratchet down</a> reefs throughout the tropics.</p> <h2>Ecological memories of heatwaves</h2> <p>Most reefs today are in early <a href="https://www.aims.gov.au/reef-monitoring/gbr-condition-summary-2020-2021">recovery mode</a>, as coral populations begin to re-build since they last experienced bleaching in 2016, 2017 and 2020. It takes about a decade for a decent recovery of the fastest growing corals, and much longer for slow-growing species. Many coastal reefs that were severely bleached in 1998 have never fully recovered.</p> <p><a href="https://images.theconversation.com/files/430169/original/file-20211104-19-1po1sc2.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/430169/original/file-20211104-19-1po1sc2.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /></a> <span class="caption">The fringing reef flat at Orpheus Island on the central Great Barrier Reef, prior to mass coral bleaching in 1998.</span> <span class="attribution"><span class="source">Bette Willis and Andrew Baird</span>, <span class="license">Author provided</span></span> <a href="https://images.theconversation.com/files/430168/original/file-20211104-27-16wyz5j.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/430168/original/file-20211104-27-16wyz5j.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /></a> <span class="caption">The same reef flat at Orpheus Island after further bleaching in 2002 and 2016.</span> <span class="attribution"><span class="source">Bette Willis and Andrew Baird</span>, <span class="license">Author provided</span></span></p> <p>Each bleaching event so far has a different geographic footprint. Drawing upon <a href="https://www.mdpi.com/2072-4292/6/11/11579">satellite data</a>, we measured the duration and intensity of heat stress that the Great Barrier Reef experienced each summer, to explain why different parts were affected during all five events.</p> <p>The bleaching responses of corals differed greatly in each event, and was strongly influenced by the recent history of previous bleaching. For this reason, it’s important to measure the extent and severity of bleaching directly, where it actually occurs, and not rely exclusively on water temperature data from satellites as an indirect proxy.</p> <p>We found the most vulnerable reefs each year were the ones that had not bleached for a decade or longer. On the other hand, when successive episodes were close together in time (one to four years apart), the heat threshold for severe bleaching increased. In other words, the earlier event had hardened regions of the Great Barrier Reef to subsequent impacts.</p> <p><a href="https://images.theconversation.com/files/430176/original/file-20211104-15-noksid.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/430176/original/file-20211104-15-noksid.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Bleached coral" /></a> <span class="caption">Bleaching is a stress response by overheated corals.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <p>For example, in 2002 and 2017, it took much more heat to trigger similar levels of bleaching that were measured in 1998 and 2016. The threshold for bleaching was much higher on reefs that had experienced an earlier episode of heat stress.</p> <p>Similarly, southern corals, which escaped bleaching in 2016 and 2017, were the most vulnerable in 2020, compared to central and northern reefs that had bleached severely in previous events.</p> <p>Many different mechanisms could generate these historical effects, or ecological memories. One is <a href="https://www.nature.com/articles/s41586-018-0041-2">heavy losses</a> of the more heat-susceptible coral species during an earlier event – dead corals don’t re-bleach.</p> <p>Nowhere left to hide</p> <p>Only a single cluster of reefs remains unbleached in the far south, downstream from the rest of the Great Barrier Reef, in a small region that has remained consistently cool through the summer months during all five mass bleaching events. These reefs lie at the outer edge of the Great Barrier Reef, where upwelling of cool water may offer some protection from heatwaves, at least so far.<a href="https://images.theconversation.com/files/430397/original/file-20211104-23-29h946.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/430397/original/file-20211104-23-29h946.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /></a> <span class="caption">Map of the Great Barrier Reef showing the cumulative level of bleaching observed in 2016, 2017 and 2020.

Did you know these 5 places could disappear in your lifetime?

<p>When places are well-known and popular – historical and modern alike – we might take it for granted that they’ll be around forever. But sadly, many of the world’s best known and culturally significant landmarks are in jeopardy. Human activity has had a devastating effect on many valued places, including massive milestones of human achievement. And many of these are so much more than just tourist attractions – they’re unique, valuable remnants of ancient times and civilizations.</p> <p><strong>The Great Barrier Reef </strong></p> <p>This massive, once-thriving coral reef has suffered enormously over recent years, with coral bleaching – caused by climate change – stripping the coral of its nutrients. This, in turn, harms the rich marine life that calls the reef home. And, of course, this also depletes it of the dazzling colours that once were a hallmark of the Great Barrier Reef’s underwater wonder. The reef remains the largest coral reef ecosystem in the world, but projections have warned that the damage to it could become irreversible in the next 10 years.</p> <p><strong>Old City of Jerusalem </strong></p> <p>One of the world’s most spiritually significant places, the Old City of Jerusalem, is in danger of disappearing, UNESCO has found. The walls of the Old City are one of its trademark features. Most famously, the Western Wall, also known as the Wailing Wall, is a valuable pilgrimage site for people of the Jewish faith, one that dates back to around 20 BCE. The Wall is the only remnant of the city’s Second Temple. The city was actually listed on UNESCO’s list of endangered cultural sites in the 1980s. Widespread urbanisation has been found to pose a significant threat to the city.</p> <p><strong>Everglades National Park </strong></p> <p>This stunning Floridian wildlife sanctuary has sadly found itself fighting for its life in recent years. As ‘the largest designated subtropical wilderness reserve’ in North America, according to UNESCO, it’s been a beloved travel destination for American citizens for decades, but the ravages of time and human activity have not been kind to it. Its survival first came into question after it was battered by Hurricane Andrew in 1993. But it’s human influence that has posed the primary threat, as water flow to the site has decreased and the impacts of pollution have increased, resulting in harmful algal blooms. Its vast, diverse wildlife is more threatened than ever before.</p> <p><strong>The Taj Mahal </strong></p> <p>It’s hard to imagine this monolithic structure, located in Agra, India, being in danger. The structure itself is in some jeopardy from the elements, but the primary reason for concern is that the Indian Supreme Court could potentially close the attraction. The court has butted heads with the government, claiming that unless the government does a better job of preserving it, they’ll have to shut it down. Pollution is visibly altering the Taj’s pristine surface. It’s also experienced insect infestations. Flies of the genus Geoldichironomus, which breed in the heavily polluted Yamuna River, neighbouring the Taj, have encroached upon the structure in recent years.</p> <p><strong>Mount Kilimanjaro’s peak </strong></p> <p>This revered mountain, one of the Seven Summits, proves that even giants can fall to climate change. While the mountain itself, located in Tanzania, isn’t in imminent danger, its iconic snow cap might vanish – and shockingly soon. Research found that the snow cap had lost 85 per cent of the total area of its ice fields between 1912 and 2007, and the remaining ice could be history as early as 2030.</p> <p><em>Written by Meghan Jones.

The first step to conserving the Great Barrier Reef is understanding what lives there

<p>Look at this photo of two coral skeletons below. You’d be forgiven for thinking they’re the same species, or at least closely related, but looks can be deceiving. These two species diverged tens of millions of years ago, probably earlier than our human lineage split from baboons and macaques.</p> <p>Scientists have traditionally used morphology (size, shape and colour) to identify species and infer their evolutionary history. But most species were first described in the <a href="https://www.nature.com/articles/027073a0">19th century</a>, and based solely on features of the coral skeleton visible under a microscope.</p> <p>Morphology remains important for species recognition. The problem is we don’t know whether a particular morphological feature reflects species ancestry, or evolved independently.</p> <p>Our new study <a href="https://www.sciencedirect.com/science/article/abs/pii/S1055790320302165">examined</a> the traditional ideas of coral species and their evolutionary relationships using “<a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1755-0998.12736">phylogenomics</a>” – comparing thousands of DNA sequences across coral species.</p> <p>Our results revealed the diversity and distributions of corals are vastly different to what we previously thought. It shows we still don’t know many fundamental aspects about the corals on Great Barrier Reef.</p> <p>And after three mass bleaching events in five years, not having a handle on the basics could mean <a href="http://elibrary.gbrmpa.gov.au/jspui/bitstream/11017/3569/4/Draft-restoration-adaptation-policy.pdf">our attempts to intervene</a> and help coral survive climate change may have unexpected consequences.</p> <p><strong>How do we know which species is which?</strong></p> <p>Despite being one of the <a href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/j.1755-263X.2010.00146.x">best-studied</a> marine ecosystems on Earth, there are fundamental knowledge gaps around the Great Barrier Reef, including:</p> <ol> <li>how many coral species live there?</li> <li>how do we identify them?</li> <li>where are they found across the vast Great Barrier Reef ecosystem?</li> </ol> <p>Finding the answers to these questions starts with accurate “taxonomy” – the science of naming and classifying living things.</p> <p>Identifying species based on how similar they look may seem straightforward. As Darwin famously said, closely related species often share morphological features because they inherited them from a common ancestor.</p> <p>However, this can be misleading if two unrelated species independently acquire similar features.

The first step to conserving the Great Barrier Reef is understanding what lives there

<p>Look at this photo of two coral skeletons below. You’d be forgiven for thinking they’re the same species, or at least closely related, but looks can be deceiving. These two species diverged tens of millions of years ago, probably earlier than our human lineage split from baboons and macaques.</p> <p>Scientists have traditionally used morphology (size, shape and colour) to identify species and infer their evolutionary history. But most species were first described in the <a href="https://www.nature.com/articles/027073a0">19th century</a>, and based solely on features of the coral skeleton visible under a microscope.</p> <p>Morphology remains important for species recognition. The problem is we don’t know whether a particular morphological feature reflects species ancestry, or evolved independently.</p> <p>Our new study <a href="https://www.sciencedirect.com/science/article/abs/pii/S1055790320302165">examined</a> the traditional ideas of coral species and their evolutionary relationships using “<a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1755-0998.12736">phylogenomics</a>” – comparing thousands of DNA sequences across coral species.</p> <p><strong>Join 130,000 people who subscribe to free evidence-based news.</strong></p> <p>Get newsletter</p> <p>Our results revealed the diversity and distributions of corals are vastly different to what we previously thought.

As Darwin famously said, closely related species often share morphological features because they inherited them from a common ancestor.</p> <p>However, this can be misleading if two unrelated species independently acquire similar features. This process, called convergent evolution, often occurs when different species are faced with similar ecological challenges.</p> <p>A <a href="https://www.nationalgeographic.com/science/phenomena/2015/02/06/why-an-ichthyosaur-looks-like-a-dolphin/">classic example</a> of convergent evolution is dolphins and the prehistoric ichthyosaurs.

We just spent two weeks surveying the Great Barrier Reef – What we saw was an utter tragedy

<p>The Australian summer just gone will be remembered as the moment when human-caused climate change struck hard. First came drought, then deadly bushfires, and now a bout of coral bleaching on the Great Barrier Reef – the third in just five years. Tragically, the 2020 bleaching is severe and the most widespread we have ever recorded.</p> <p>Coral bleaching at regional scales is caused by spikes in sea temperatures during unusually hot summers. The first recorded mass bleaching event along Great Barrier Reef occurred in 1998, then the <a href="http://www.bom.gov.au/climate/change/archive/media99.shtml">hottest year on record</a>.</p> <p>Since then we’ve seen four more mass bleaching events – and more temperature records broken – in 2002, 2016, 2017, and again in 2020.</p> <p>This year, February had the<a href="https://www.abc.net.au/news/2020-03-15/cyclone-great-barrier-reef-bleaching-record-seas-temperatures/12050102"> highest monthly sea surface temperatures</a> ever recorded on the Great Barrier Reef since the Bureau of Meteorology’s records began in 1900.</p> <p><strong>Not a pretty picture</strong></p> <p>We surveyed 1,036 reefs from the air during the last two weeks in March, to measure the extent and severity of coral bleaching throughout the Great Barrier Reef region. Two observers, from the ARC Centre of Excellence for Coral Reef Studies and the Great Barrier Reef Marine Park Authority, scored each reef visually, repeating the same procedures developed during early bleaching events.</p> <p>The accuracy of the aerial scores <a href="https://www.nature.com/articles/nature21707?dom=icopyright&amp;src=">is verified</a> by underwater surveys on reefs that are lightly and heavily bleached. While underwater, we also measure how bleaching changes between shallow and <a href="https://www.nature.com/articles/s41467-018-05741-0">deeper reefs</a>.</p> <p>Of the reefs we surveyed from the air, 39.8% had little or no bleaching (the green reefs in the map). However, 25.1% of reefs were severely affected (red reefs) – that is, on each reef more than 60% of corals were bleached. A further 35% had more modest levels of bleaching.</p> <p>Bleaching isn’t necessarily fatal for coral, and it affects <a href="https://theconversation.com/how-much-coral-has-died-in-the-great-barrier-reefs-worst-bleaching-event-69494">some species more than others</a>. A pale or lightly bleached coral typically regains its colour within a few weeks or months and survives.</p> <p>But when bleaching is severe, many corals die. In 2016, half of the shallow water corals died on the northern region of the Great Barrier Reef <a href="https://www.nature.com/articles/s41586-018-0041-2">between March and November</a>. Later this year, we’ll go underwater to assess the losses of corals during this most recent event.</p> <p>Compared to the four previous bleaching events, there are fewer unbleached or lightly bleached reefs in 2020 than in 1998, 2002 and 2017, but more than in 2016. Similarly, the proportion of severely bleached reefs in 2020 is exceeded only by 2016. By both of these metrics, 2020 is the second-worst mass bleaching event of the five experienced by the Great Barrier Reef since 1998.</p> <p>The unbleached and lightly bleached (green) reefs in 2020 are predominantly offshore, mostly close to the edge of the continental shelf in the northern and southern Great Barrier Reef. However, offshore reefs in the central region were severely bleached again. Coastal reefs are also badly bleached at almost all locations, stretching from the Torres Strait in the north to the southern boundary of the Great Barrier Reef Marine Park.</p> <p>For the first time, severe bleaching has struck all three regions of the Great Barrier Reef – the northern, central and now large parts of the southern sectors. The north was the worst affected region in 2016, followed by the centre in 2017.</p> <p>In 2020, the cumulative footprint of bleaching has expanded further, to include the south. The distinctive footprint of each bleaching event closely matches the location of <a href="https://www.nature.com/articles/nature21707?dom=icopyright&amp;src=">hotter and cooler conditions in different years</a>.</p> <p><strong>Poor prognosis</strong></p> <p>Of the five mass bleaching events we’ve seen so far, only 1998 and 2016 occurred during <a href="http://www.bom.gov.au/climate/updates/articles/a008-el-nino-and-australia.shtml">an El Niño</a> – a weather pattern that spurs warmer air temperatures in Australia.</p> <p>But as summers grow hotter under climate change, we no longer need an El Niño to trigger mass bleaching at the scale of the Great Barrier Reef. We’ve already seen the first example of back-to-back bleaching, in the consecutive summers of 2016 and 2017. The gap between recurrent bleaching events is shrinking, hindering a full recovery.</p> <p>After five bleaching events, the number of reefs that have escaped severe bleaching continues to dwindle. Those reefs are located offshore, in the far north and in remote parts of the south.</p> <p>The Great Barrier Reef will continue to lose corals from heat stress, until global emissions of greenhouse gasses are reduced to net zero, and sea temperatures stabilise. Without urgent action to achieve this outcome, it’s clear our coral reefs will not survive business-as-usual emissions.</p> <p><em>Written by Terry Hughes and Morgan Pratchett.

New $10 million floating hotel lets you stay in the Great Barrier Reef

<p>A new $10 million floating hotel on the Great Barrier Reef is offering Australia’s first underwater suites, which means tourists are able to wake up to the natural wildlife.</p> <p>The <a href="https://cruisewhitsundays.com/experiences/reefsuites/">Reefsuites</a> at Hardy Reef are set to be a “game changer” for the local tourism industry, according to Tourism Minister Kate Jones.</p> <p>“This will be one of the most iconic tourism projects in the world,” she said in a <a href="http://statements.qld.gov.au/Statement/2019/8/1/new-attraction-to-bring-thousands-of-tourists-to-the-whitsundays">statement</a>.</p> <p>“We want to invest in tourism attractions that we know will attract more visitors to the Whitsundays and support local jobs – this project will achieve just that.”</p> <p>The two exclusive suites sit four metres below the surface, with just three inches of glass separating you from the reef life outside.</p> <p>At night, outside lights illuminate the waters so you can see what happens in the reef after dark.</p> <p>Floor to ceiling windows are a part of the experience so you don’t miss anything.</p> <p>The project began in 2017 as the pontoon was reconstructed after damage from Cyclone Debbie. The project was developed by Cruise Whitsundays and the Queensland Government.</p> <p>“Today is a landmark moment for Australia,” says Luke Walker, from Journey Beyond, the parent company of Cruise Whitsundays.</p> <p>“We are extremely privileged to have access to such a truly breathtaking and remote part of Australia and to provide both local and international guests the chance to gain a deeper appreciation of our wonderful Great Barrier Reef,” he says.</p> <p>Each Reefsuite has a two-person capacity, but guests can also camp under the stars as the roof of the pontoon is set up to accommodate a dozen queen beds in custom-built canvas canopies. Up to 28 visitors at a time can be on the pontoon.</p> <p>Scroll through the gallery to see the pontoon and how the suites will look underwater.</p> <p><em>Photo credits: <a href="https://cruisewhitsundays.com/experiences/reefsuites/">Cruise Whitsundays</a></em></p>

Mums slam "secretly underwhelming" tourist attractions

<p>Mumsnet is a forum where mothers gather together and voice their opinions on a range of topics, including what tourist destinations are “secretly underwhelming”.</p> <p>This topic spread like wildfire, and the answers will either have you agreeing or shaking your head in disapproval.</p> <p>In a thread titled “What famous landmark or must visit place/thing were you secretly underwhelmed by?”, Mumsnet user Midge1978 elaborates on her provocative question.</p> <p>“I went to Stonehenge this year and whilst I was trying to get in touch with my inner druid, trying to project historical importance and mystery onto the place, I just couldn’t escape the feeling that I was just looking at some very old stones and it was actually (whisper) a little bit boring!!” she said.</p> <p>“My husband thought it was all marvellous though so I have never told him!!!”</p> <p>Others were quick to voice their opinions, even knocking the Great Barrier Reef.</p> <p>“The Grand Canyon and the Great Barrier Reef,” said one mum, declining to elaborate.</p> <p>Another mum seconded her, “Yes, Great Barrier Reef – sadly, and only because there is so much coral die back it is depressing. Genuinely disappointing as diving here was a long-held dream of mine.”</p> <p>Paintings were even on the list, with some mentioning <em>The Scream</em>.</p> <p>Midge agreed and shared her experience of seeing <em>The Mona Lisa</em>.</p> <p>“Oh gosh yes The Mona Lisa – queued for bloody ages to see a small dull painting that I had already seen emblazoned over every item in the gift shop!” she said.</p> <p>“The pyramids/sphinx,” said another mum. “I expected a mystical, magical place in the desert. I got … lots of beggars/sales people/McDonalds. Gutted.”</p> <p>Another mum agreed: “Yep Midge, sorry. I have a fabulous photo that everyone aaahs over of the sphinx with a pyramid behind it and a clear blue sky. When I look at it all I can think is “I was standing in front of McDonald’s when I took that …”</p> <p>However, some comments called out the lack of culture in Australia.</p> <p>“The whole of Australia frankly – no culture at all apart from the Aboriginal history,” someone wrote.</p> <p>“The Aborigines were treated like sh*t by the white Australians which disgusted me. Didn’t hear a single one have a good thing to say about the indigenous population – notice how there’s never any on Australian TV.”</p> <p>New Zealand made the list too.</p> <p>“Another vote for the various different landmarks in New Zealand. I went expecting awe-inspiring views and to be blown away by the scenery, but I wasn’t,” one said.</p> <p>“It’s all really nice, don’t get me wrong. But the mountain views aren’t as good as those in the European Alps, the fjords aren’t as good as Norway’s, various bits of Scotland etc. It’s like a 7 out of 10 of everything all in one country, compared to 9 or 10 out of 10 of other things scattered around the world.”</p>

This destination is the crowning glory of the Great Barrier Reef

<p>Lying in the heart of one of Australia's greatest national treasures, the Great Barrier Reef, the Whitsunday Islands are its crowning glory. These 74 tropical islands prove that the region’s beauty is just as rich above water as below it. It’s one of the most prized and revered natural destinations in Australia.</p> <p>With so many islands to discover and explore, many of them completely secluded, the choice of where to stay and what to do is almost endless. But you can’t leave this incredible environment without taking a peek under the water at the pristine reef, finding an isolated bay and settling in for a beach picnic, or trekking the national park trails that cover many of the islands.</p> <p>From the resorts on Hamilton Island to the white silica sands of Whitehaven Bay, the heart-shaped reef and incredible marine life, the Whitsundays are best explored by foot, by plane and, of course, by boat.</p> <p>Named after Captain James Cook recorded his sighting of the islands in his diary as ‘Whitsunday Passage’, the passage wasn’t actually discovered until Whit Monday, as the International Date Line had not yet been established. Sailing through the islands is still one of the most popular ways to discover them, and many visitors today would have the same view of the beautiful passage that Cook enjoyed in 1770.</p> <p>“Hamilton Island is without doubt the ultimate getaway! Perched on the edge of the Great Barrier Reef and nestled among the Whitsunday Islands, it offers the discerning traveller an experience of a lifetime. With stunning coral reefs, inviting beaches and perfect weather, this destination has to be at the top of everyone’s bucket list … just add champagne and ice!” - Viv Chelin, Cooma, New South Wales</p> <p><strong>What to do:</strong></p> <ul> <li>Snorkel or dive from any number of sites around the Whitsundays for some of the world’s best underwater experiences.</li> <li>Spend some time on Hamilton Island, the commercial heart of the islands and where resorts, shops, restaurants, bars, cafes and the airport can all be found.</li> <li>Get pampered at one of the many day spas on the islands; relaxation is the name of the game here.</li> <li>Learn about the Whitsundays’ original inhabitants, the Ngaro people, and follow the Whitsunday Ngaro Sea Trail walk to discover their history and culture.</li> </ul> <p>“One of our favourite places in Australia is the Whitsunday islands. We’ll never forget our adventure with our friend, yachtsman Jesse Martin, who wrote himself into the history books by sailing around the world when he was just 17 years old. We chartered a catamaran with him and set off for a couple of days exploring the islands.</p> <p>Leaving from Airlie Beach, we headed straight into the wind and set sail, wanting to go in one direction, but the wind had other ideas. Skipper Jesse declared with a smile, ‘Sometimes you’ve just gotta go where the wind takes you …’ (wisdom we still use today). And with that we decided to just make everything up as we went along! That’s the beauty of the Whitsundays: while you might encounter all manner of weather, there are so many islands and sheltered inlets where you can anchor. We headed to a place called Nara Inlet on Hook Island and, after checking out some Aboriginal rock art, settled in for the night. As the sun started to set, we enjoyed a barbie, while Jesse played guitar on the front deck. There was not another boat in sight. With the gentle slapping of the water against the hull, it was one of the best sleeps we’d ever had. The next day we sailed to Hamilton Island for a coffee. It was quite weird just being able to pull up and moor the boat, but it really was as simple as that.” – Jen and Clint</p> <p><img width="175" height="214" src="https://oversixtydev.blob.core.windows.net/media/7815921/1_175x214.jpg" alt="1 (94)" style="float: right;"/></p> <p><em>This is an edited extract from </em>Australia’s Ultimate Bucket List<em> by Jennifer Adams &amp; Clint Bizzell published by Hardie Grant Books RRP $29.99 and is available in stores nationally.</em></p>

Great Barrier Reef valued at $56 billion

<p>A new Deloitte Access Economics report has found the total asset value of the Great Barrier Reef to be $56 billion.</p> <p>The economists calculated the World Heritage site’s economic, social and iconic brand value to reach the staggering figure.</p> <p>Many Australians believe the reef is priceless but Deloitte arrived at the figure after a six-month analysis that drew on economic and scientific sources as well as international surveys.</p> <p>At $29 billion, tourism was found to be the greatest contributor to the overall value. $23.8 billion of the reef’s value came from “indirect or non-use value” which means people who haven’t yet visited the reef but value knowing it exists. $3.2 billion of its value was attributed to recreational users such as weekend divers.</p> <p>Commissioned by the Great Barrier Reef Foundation, the report found the reef added $6.4 billion of economic value to the Australian economy in 2015-16.</p> <p>The reef employs 39,000 people directly but there are also 64,000 jobs linked to it nationally. In comparison, National Australia Bank creates 34,000 direct jobs, Telstra 33,000 and Qantas 26,000.</p> <p>Great Barrier Reef Foundation director Steve Sargent said no other Australian asset contributed as much value to “Brand Australia”.</p> <p>"At $56 billion, the reef is valued at more than 12 Sydney Opera Houses," he said.</p> <p>"This report sends a clear message that the Great Barrier Reef – as an ecosystem, as an economic driver, as a global treasure – is too big to fail."</p> <p>Former US vice-president Al Gore deemed the report as a necessary look at the reef’s value.</p> <p>"Any failure to protect this indispensable natural resource would have profound impacts not only to Australia but around the world," he said.</p> <p>Deloitte Access Economics partner and report author John O’Mahony labelled the reef as irreplaceable.</p> <p>"With the reef under threat, our report is a major step in looking to value nature's significance in monetary terms and using this information to help inform what we do to protect and save important natural assets."</p> <p>The study used various economic techniques including input-output tables, econometrics, willingness to pay analysis, sensitivity and the Brand Asset Valuator.</p> <p>In the past two years, two-thirds of the reef have been impacted by unprecedented coral bleaching. </p>

Desperate plea for government to save the Great Barrier Reef

<p>WWF Australia has issued a desperate plea for supporters to write to the government and urge Prime Minister Malcolm Turnbull to do more to <a href="http://www.oversixty.com.au/travel/domestic-travel/2016/10/5-australian-world-heritage-sites-everyone-should-visit/"><span style="text-decoration: underline;"><strong>save the Great Barrier Reef</strong></span></a>.</p> <p>This follows research released in early April which suggest a “substantial loss” of coral was expected in 2017, with 90 per cent of the reef already covered in bleached coral.</p> <p>Professor Terry Hughes from the ARC Centre of Excellence for Coral Reef Studies at James Cook told Storyful, “Last year most of the severe bleaching was in the northern 700km stretch of the Great Barrier Reef. This year tragically, that damage has extended much further south. So in 2017 most of the bleaching is the central section of the Great Barrier Reef.</p> <p>“If we look at the last two years in combination, fully two-thirds of the Great Barrier Reef, the northern third and the middle third, is now severely damaged by global warming.”</p> <p>The video above depicts the incredible colourful ocean life on display in the reef, in comparison to the desolate bleached coral. It’s one thing to read about the damage to the reef, but seeing it makes you really understand the gravity of the situation.</p> <p>For more information on the damage to the reef and what you can do to help, <span style="text-decoration: underline;"><a href="http://www.wwf.org.au/what-we-do/oceans/great-barrier-reef#gs.T0dlAUY" target="_blank"><strong>click here</strong></a></span>.</p> <p>Do you think Australia has done enough to protect the Great Barrier Reef?</p> <p><em>Video credit: WWF-Australia via Storyful</em></p>

3 tips for older job seekers

<p>Perhaps you’re not ready to retire just yet or seeking a part-time job to tie you over as transition to retirement, whatever the case here are some great tips to make yourself stand out of the crowd in the job market.</p> <p><strong>1. Be tech savvy</strong></p> <p>Not only is the digital world used in all aspects of business and working, but it is also a key platform for employers to scope out their potential employee. Gone are the days of handing in a paper resume, now an employer will look for a job candidate on their online profiles such as websites like LinkedIn and even social media. Before you go for a job interview, check your social media to make sure no information that you don’t want a future employer seeing can be accessed by a user that isn’t your “friend” or in your network. If you haven’t signed up with <a href="https://au.linkedin.com/" target="_blank"><strong><span style="text-decoration: underline;">LinkedIn</span></strong></a> and you are going for an interview, you should create a profile. Demonstrating you have the digital skills necessary in the modern workforce shows a potential employer your adaptable in our tech-saturated world. By always growing your skills and being teachable, you don’t put a ceiling on your intellect.</p> <p><strong>2. Sell yourself effectively</strong></p> <p>Entitlement is a character trait that marks a red flag for any potential employer. To avoid appearing entitled, practice articulating the benefits you have from your years of experience in the workforce. Although you might have a wealth of experience in the workforce, focus your time on selling the experience that is relevant to the job role you are interviewing for. It is easy to ramble on in an interview but by honing in on specific skills and experience that have prepared you for this role, you will gain an upper-hand in the interview process. Remember also to always appear optimistic and motivated, they are two character traits that are welcomed in any business.</p> <p><strong>3. Don’t dwell too much on achievements from decades ago</strong></p> <p>Employers generally want to hear about your achievements in the last ten years. You can also talk about your academic qualifications as that is important information. If you want to talk about experience that happened quite some years ago, try not to mention specific dates or time periods. Spend the majority of your time in the interview talking about your recent accomplishments and what skills you have.</p> <p>Have you had to look for a new job later in life? What was your experience like? Let us know in the comments below. </p>

The Aussie escape perfect for nature lovers

<p>The place is packed. Absolutely chocka.</p> <p>Heron Island, a tiny coral cay 90kms from Gladstone in central Queensland, is billed as an isolated tropical retreat where you can escape from the rest of the world and enjoy the Great Barrier Reef.</p> <p>But when our family of five lurch off the 34-metre catamaran that gets you there, we have barely taken a step ashore before being hit by the crowds. It's standing room only, and these overseas guests are noisy and, well, they smell.</p> <p>In fact, the "crowds" are part of the reason we're here: because this tiny piece of paradise is packed with wildlife: up to 100,000 black noddy terns are in residence, nesting in the ancient pisonia​ trees that you walk past within seconds of coming ashore.</p> <p>The birds are, literally, in your face, complete with fluffy chicks that are being sat on by their mums for protection.</p> <p style="text-align: center;"><img width="498" height="245" src="https://oversixtydev.blob.core.windows.net/media/34588/image__498x245.jpg" alt="Image_ (138)"/></p> <p>Dashing crazily along sandy pathways are buff-banded rails, looking like some kind of demented chickens, chasing each other to and fro.</p> <p>And then, at night, in come the wedge-tailed shearwaters (muttonbirds​), which nest at ground level, and whose eerie cries caused sailors to believe the island was haunted. Then, of course, there's the eponymous eastern reef egrets​, which were first spotted on the island in 1843.</p> <p>Ironically, given its past as a turtle cannery in the 1920s, the biggest tourist drawcard today is not the prolific birdlife, however, it's the turtles.</p> <p>Between December and March, Heron is home to one of nature's greatest – and, it has to be said, clumsiest​ – miracles.</p> <p>The white coral sands act like a homing beacon for hundreds of green turtles (and the occasional loggerhead). The reptiles, so graceful in the water, drag themselves up the beaches at night to lay scores of ping-pong ball-sized white eggs.</p> <p>This is a ritual hundreds of thousands of years old and is a living link to primitive life forms emerging from the sea. There's something oddly comical about it, as turtles, which have travelled up to 3000kms to get here, move with all the grace of a sack of potatoes as they lumber up the sand dunes.</p> <p>Queensland Environment &amp; Heritage Protection volunteer researcher Janine Ferguson has spent more than four decades working on the conservation of turtles. During that time she has become close to her charges, often referring to her "girls".</p> <p>"You do get to know some of them. They come back year after year and you do get a bit of a sense of them and their personality," she says.</p> <p>The greens lay from mid-December through to mid-January, with hatchlings​ emerging about eight to 10 weeks later.</p> <p>The odds are stacked against them. From the moment the credit card-sized hatchlings​ emerge from their nest, the battle for life begins.</p> <p>Squadrons of birds hover overhead, waiting to pick them off before they've even made it to the water. Their first journey is an epic one, as they often emerge high in the sand dunes and have to instantly orient themselves, using their sight to head for the brightest object – which should be the sand and the water.</p> <p>Even if they safely make the run through the dunes, once they finally hit the water, tiny heads bobbing as they come up for air, reef sharks are waiting to scoop them up. No wonder it's estimated that only one in 1000 make it to maturity.</p> <p>Unless you're conducting turtle research, access to the island comes exclusively via Heron Island Resort, the only accommodation on this small piece of land, which is not open to daytrippers​. The resort has 109 rooms and can accommodate up to 300 people, although even in peak season it feels half empty.</p> <p>It's run by US firm Delaware North, which also operates El Questro​ station and Lizard Island in Australia.</p> <p style="text-align: center;"><img width="498" height="245" src="https://oversixtydev.blob.core.windows.net/media/34589/image__498x245.jpg" alt="Image_ (139)"/></p> <p>It's about as laidback​​ as you can get, with no mobile reception, extremely limited Wi-Fi and no locks on the doors. "With no daytrippers​, security isn't really an issue," says long-time resident and island guide Jason Killen.</p> <p>The resort has a range of rooms, from one and two-bedders, through to a larger beach house. We stay in one of the reef rooms. These rooms have no airconditioning but good ceiling fans, and are well shaded by pisonia​ trees.</p> <p>The best part is it's only a few steps to a gorgeous white coral beach. Our room has a decent queen-size bed, and two singles in a recess with a sliding screen to close it off. You can make tea and coffee and there is a bar fridge.</p> <p>The resort is low-rise and designed to fit in among the trees and minimise impact on the wildlife. Power comes from a generator, they make their own drinking water and wastewater is treated before discharge. The island has an advanced eco-certification by Ecotourism Australia.</p> <p>With all the birds nesting above your head in the trees, guests quickly divide into two groups: those who use brollies and those who don't. We choose to run the gauntlet and the only person who gets nailed is my eldest daughter Grace. Unluckily for her she gets hit twice.</p> <p>There is the large poolside Baillies Bar, which has snacks, cocktails, an espresso machine, pool tables and a giant chessboard. Nearby is the Shearwater Restaurant, which offers a la carte and buffet dining options.</p> <p>When you're not bird or turtle watching, the water is the big drawcard, with plenty of options for snorkelling and diving.</p> <p>This island is surrounded by a shallow fringing reef, so finding a spot to snorkel is not difficult. And on low tide, reef walks are popular.</p> <p>One of the highlights is swimming out over the main harbour to the wreck towed there in 1943 by Captain Christian Poulsen​. On the way you pass dozens of rays, reef sharks, schools of trevally, giant clams and scores of small tropicals.</p> <p>Grace is simultaneously keen and terrified to swim with a shark, so she holds my hand tightly as we fin through the water. When I quickly spot a black tip circling nearby I can't find her – until I realise she has already seen it and has clambered onto my back.</p> <p>There are multiple dive trips each day on the island's fringing reef and the adjacent Wisteria Reef.</p> <p>One day I go diving out to Coral Canyons, just outside the main harbour. It is an epic dive, consisting of layers of plate, stag and brain corals, and is rich in marine life, with turtles, nudibranchs​, clown fish and damselfish.</p> <p>Another dive site, Heron Bommie, has been singled out by French underwater legend Jacques Cousteau​ as one of his top 10 sites in the world.</p> <p>If you want to see the marine life but keep your feet dry, you can either hire a clear plastic kayak or take a tour on a glass-bottomed boat called iSpy​ that visits many of the dive sites around the reefs. Fishing charters are also available.</p> <p>For those not so interested in water or nature activities, the island has the Aqua Soul spa, offering facials, massage and steam treatments.</p> <p>Children under 12 stay for free, which probably explains why the place is full of families. However, the kids' meals are basic. Breakfasts are the pick, with a range of fresh fruit, cereals, pastries and hot foods on offer, including made-to-order omelettes.  However, lunch and dinner feature limited buffet choices, which had our 12-year-old begging for the a la carte menu.</p> <p>A la carte offers fresh fish, meat and vegetarian dishes. However, while the food is decent, it's fair to say you wouldn't come here for that alone. It's about getting up close and personal with all the aquatic and bird life. Just don't mention turtle soup.</p> <p><em>Written by Liam Phelan.

5 tips for overcoming a language barrier overseas

<p>While English is spoken in most corners of the world these days (at least in some capacity), there are still plenty of places where you might find it difficult to communicate if you only know the one language. The good news is you don’t need UN interpreter levels of language mastery to get your point across in a non-English speaking country.</p> <p>Here are five tips for dealing with the language barrier overseas.</p> <p><strong>1. Learn a handful of simple words/phrases</strong></p> <p>Taking the time to learn a couple of key words and phrases before you head to the airport can be a real lifesaver overseas. Even something as simple as knowing how to say things like, “Hello”, “Thank you” and, “Do you speak English?” can make life much easier.</p> <p><strong>2. Check out some of the translation apps</strong></p> <p>Some of these get a bad rap for producing inaccurate results, but if you know how to use them translation apps can be a godsend. We’d recommend <a href="/entertainment/technology/2016/07/turn-your-phone-into-a-personal-language-translator/" target="_blank"><strong><span style="text-decoration: underline;">Google Translate</span></strong></a> and <a href="/entertainment/technology/2016/08/how-to-learn-a-new-language-in-five-minutes-a-day/" target="_blank"><span style="text-decoration: underline;"><strong>Duolingo</strong></span></a>. Google Translate can be used as a store of useful phrases (and translator in a tight spot), while Duolingo is the perfect way to practice the local tongue before you go.</p> <p><strong>3. Use hand gestures and body language</strong></p> <p>You might not feel like an expert when you’re doing it, hand gesture and miming can be a clever way to get people to understand you. Sure, you don’t want to be embarking on an impromptu game of charades every time you order your dinner but a simple action like flapping your arms like a chicken can help ensure you’ve ordered the right meat.</p> <p><strong>4. Pointing can sometimes help</strong></p> <p>It’s perhaps the simplest gesture that can be performed by a human, but it’s also one that probably conveys the most information without words. Pointing can help someone realise what you want to eat or where you want to go. That being said, there are some countries where pointing is frowned upon, so make sure you bone up on local customs.</p> <p><strong>5. Most importantly, be courteous</strong></p> <p>In the end of the day, a little bit of courtesy is best bet when trying to communicate in a non-English speaking country. Instead of raising your voice and causing a minor international incident, keep calm, show some poise and use the steps outlined above to communicate as best you can. You’ll be surprised how far you can get. </p> <p>Have you ever run into strife communicating in a country where you don’t know the language? How did you cope?
